called loose leaf record books.

In binders of this type hitherto known the binding posts have beenindividually pivotally mounted on pintles at their opposite ends. Theresult of this construction has been that it is a difficult matter tohold all of the posts inthe same plane when it is desired to insert anew sheet in the binder.

Also binders of this character which have solid posts of necessity mustalways have the two covers a given spaced distance apart with the resultthat when there is in position in the binder a number of sheets lessthan the capacity of the binder they will not be firmly held injuxtaposition to each other and the book will be inconvenient to use.

Also when books of this character are used it is frequently necessarythat a full complement of sheets be inserted in the binder or withdrawntherefrom and with the usual type of binder this is a difficultoperation because it is hard to keep the holes in the sheets inalinement so that they may be passed readily over the posts. 1

The main object of my invention is to pro- I vide a binder in which theposts will be permanently held in the same plane irrespective of themovement of the posts with reference to the covers of the book.

Another object of my invention is to provide an adjustable fly leafwhich will at all times hold in juXta-position the sheets in the binderirrespective of the number of such sheets to prevent undue wear of theperforations of the sheets.

Another object of my invention is to provide co-acting supplemental flyleaves whereby a full set of sheets may be inserted in or withdrawn fromthe binder with ra idity and ease.

Another object is to provide in loose binders of this type, which arelargely used for filing photographed record prints, an eflicient meansfor compressing and thus straightening and flattening such prints,which, when fresh, are more or less crimped or warped.

Other objects and advantages relating to size, shane and arrangement ofparts all as will more fully appear from the following description takenin connection with the accompanying drawings in which:

Figure 7 isa perspective view of my supplemental fly leaves.

Figure 8 is a erspective view, partial y broken away, of my binder andone of the supplemental fly leaves illustrating the way in which the flyleaves are used with the binder.

Figure 9 is a section on line 99 of Figure 7 with the supplemental flyleaves in closed position and with a set of leaves insertedtherebetween.

My device consists of covers 1 and 2, joined together by a flexible back7, formed of heavy cardboard or other appropriate material andpreferably covered on the outside by a cover -3-- of leather or otherdurable material, and also preferably covered on the inside by a coverof an appropriate durable material. An end plate 5 is positioned on theinner end of cover 1 and is held in position by rivets 6- or otherappropriate means. End plate 5 extends inwardly beyond the inner edge ofcover 1 and is returned bent to form a cylindrical journal 8 for apurpose hereinafter to be described. Journal 8 is cut away, as shown at9- on Figure 4, to receive the ends of the posts hereinafter to bedescribed.

A second end plate 1 is positioned along the inner edge of cover 2 andis fastened therein by means of rivets --11.

, posts 13-- End plate 10 extends inwardly beyond the inner edge ofcover -2- and is returned bent to form a housing 17-- for apintlecarrying member hereinafter to be described. End plate 10- is cutaway, as shown at -12 on Figure 5, to permit the insertion therein ofposts hereinafter to be described.

Posts -13-- are preferably formed of an unbendable material rectangularin cross sc tion and having reduced ends -1 1 with holes 15 through eachof the reduced ends 11. A plurality of posts -13, in this case shown asfive, are rigidly secured by welding or other appropriate means to acylindrical rod -16 and are positioned so as to be always in the sameplane irrespective of the rotation of rod 16. Rod -16 is rotatablypositioned in journal 8 of end plate 5 with the posts 13 positionedthrou h the cut-away portions 9 of housing 8.

A pintle-carrying member -18 carrying a plurality, in this case shown asfive, of pintles 19 is slidably positioned inhousing -17 in such amanner that in one position the pintles -19- will extend across theopenings 12- and in another position will be withdrawn from openings 12.The

position, extend into openings 12 for the reception in holes -15- ofpintles 19'- for the purpose of locking the posts in position.Pintle-carrying member -18 has at one end a handle 20-- by which it maybe moved back and forth in housing -17. lock -21- is positioned adjacentto pintlecarrying member 18-. Pintle-carrying member 18- has in the edgeadjacent to lock 21- a slot -22 for the reception of bolt -'23 of lock21-. When pintlecarrying member 18 is in position with intles -19 inholes 15, as shown in igure 4, the bolt -23 will be in slot 22 and willprevent the retraction of pintlecarrying member 18. When it is desiredto retract pintle-carrying member 18- a'key, not shown, is inserted inlock 21- and bolt -23 is retracted and held in the retracted position bya detent 24,

as shown in Figure 5, and pintle-carryingv member --18- may then beretracted to removev pintles -l9ifrom holes 15-- thereby releasing posts-+13-. When pintlecarrying member 18- is retracted to its outwardposition the inner edge of slot 20 will contact with detent 24 whichwill release bolt -23. Bolt --23- however, can not enter slot 22- untilpintle-carrying member 18 has again been pushed forward to bring slot22- in registration wlth bolt -23. When this is done bolt -23 willautomatically enter slot -22- and lock pintle-carrying member -18-- inposltlon.

when the binder is in the closed" A action of springs Adjustable flyleaf 25- made of heavy canvas or other appropriate material and ofapproximately the same size and shape as cover -1-, carries at its inneredge a h0us-. ing 26 secured thereto by rivets 27 or other appropriatemeans. Housing 26 is provided with a plurality, in this case shown asfive, of holes 28 to permit the passage therethrough of posts 13. Aspring locking member 29 is positioned in housing -26 and consists of ametal strip -3Q- which carries on its end a spring 31-. Spring 31 beingso positioned that in the locked position it will extend into a hole 28sufficiently far to press against a post -13- to hold fly leaf 25-- frommovement on post 13-. Another strip ing 26 opposite to that in whichstrip 30 is positioned and carries on its end a similar spring 33 whichin the locked position extends into another opening -28- sufficientlyfar to press against another post -13 to also prevent movement of flyleaf 25-. Strips 30 and 32 are connected to a bell-crank 3L by means oflinks -35'- and 36. Bellcrank 34-- is pivotally mounted on a pin 37which is positioned in housing 26- thereby forming a toggle jointbetwe'en strips -30- and 32. Springs 31 and 33- have their ends bentupwardly so that when fly leaf -25- is placed on posts -13- it may bepressed downwardly against the -31 and 33-. The ends of springs 31 and33- which bear against their respective posts -13 being bent upwardlywill exert a pressure against such posts -13 when it is attempted toraise fly leaf --25--, and in order to raise fly leaf 25 it will benecessary to rotate bell-crank -3 1 which through links --35- and 36-will retract strips -30- and-Q12?- and will withdraw springs -31 and-33' from registration with their respective posts -13-, and the flyleaf can then be raised.

Supplemental fly leaves -38-- consist of a bottom portion -39- and a topportion -40 both constructed of a flexible heavy paper or otherappropriate material and are of approximately the same size and shape ascover 1-. Bottom portion 39 carries on its rear edge a plate -4:1 whichis provided with a plurality of holes, in this case five, 42- to permitthe passage therethrough of posts 13-. A plurality, in this case shownas four, of cylindrical posts 43 are rigidly positioned in plate -41- inspaced relation and are of an appropriate height to extend through thefull complement oft eaves .44, when my binder is filled to capacity.Posts 43- are internally threaded on their upper end, as shown at -45-in Figure 9, for the reception of -32 is positioned in the end ofhousscrews -46 for a purpose hereinafter described. Top portion 40-'carries on its rear edge a plate 4:'( which is provided with aplurality, in this case shown as five, of holes 48 to permit the passagetherethrough of posts 13-. Plate --47 is also provided with a plurality,in this case shown as four, of cylindrical holes 49- to permit thepassage therein of the upper ends of posts -43--.

Operation 7 of posts 13- and posts 43, may then be placed in position onp0sts 13'- or removed therefrom after which adjustable fly leaf -25-will be placed in position on pos -.-13- on top of sheets -44 andpressed downwardly until it contacts with the upper one of sheets -4=4to hold such sheets in juxta-position. Cover 2- will then be replaced onposts -13 and pintle-carrying member -18- pushed inwardly to lock cover.

2- to posts -.13-.

When it is desired to temporarily withdraw a full complement of sheets-44- from the binder, cover -2- will be removed from posts -'13 andadjustable fly leaf-25- also removed from posts 13- in the manner justdescribed. Bottom rtion -39 will then be placed on top 0 sheets 44 andposts -43 inserted through holes -51- and bottom portion --39- presseddownwardly until it contacts with the upper sheet of sheets 44-. Bottomportion 39'- carrying sheets -44- may then be lifted from posts 13.Upper portion 40 will then be placed on the bottom one of sheets withposts 43-- extending into holes -49 and screws --4=6 will then be placedin the threaded ends of posts -43 to lock drawing and the binder againlaced in the locked position in the manner heretofore described. Iclaim:
